When you open the application, health steps are not displayed and not updated, and sometimes even when you open it, everything freezes and crashes

Hi SW1Z1K,

Thanks for the info. You can force an app to close by completing the steps listed here: Close an app on your iPhone or iPod touch

Also, let's make sure that the "Fitness Tracking" and "Health" options are both enabled under Settings > Privacy > Motion & Fitness

Lastly, turn "Fitness Tracking" and "Health" off under Settings > Privacy > Motion & Fitness, then turn them back on. Once done, test for the issue again.

Take care

Hello SW1Z1K,

Welcome back to Apple Support Communities!

To learn even more about the situation, does a normal restart of the iPhone have any impact on the issue?

To confirm, you're using iOS 15.4.1 at this time? Do you have any apps installed that might alter the Heath app?

Do any other apps have this issue, or only the Health app?

The more details you can provide about the situation, the better equipped we are to assist.

Cheers!

Hi SW1Z1K,

With your Health app not updating data and becoming unresponsive, start by force quitting and re-opening the app. Make sure you're running the latest software in Settings > General > Software Update. Restart iPhone.

If your activity is synced from another device such as an Apple Watch, open the Health app > tap on your profile in the upper-right corner. Scroll down to Devices and make sure that the device is listed. If a device is listed, you can tap on the device and the waling activity to view information to ensure it is available from the other device.

Regards.

Hi SW1Z1K,

In this case, it would be best to contact Apple Support directly. You can reach out from Get Support or using the direct phone number for your region from Contact Apple for support and service.

Best of luck.
